I personally feel the LCP is in a different league completely when it comes to pocket carry. The snub nosed revolver is much heavier and larger. That being said the snub nose has so much versatility as a primary carry piece, much more so than the LCP. It is capable of being carried in a pocket, better on the hip, and you have more ammo selection. If you were looking for a pistol for pocket carry only I would say the LCP hands down. For a versatile primary carry piece a 2-3 inch revolver is the better choice. I think a subcompact 9mm like the G26 or M&P 9C is a better choice still but between the two, the revolver.
